    kconfig: add savedefconfig · 7cf3d73b
    Sam Ravnborg authored
    savedefconfig will save a minimal config to a file
    named "defconfig".
    The config symbols are saved in the same order as
    they appear in the menu structure so it should
    be possible to map them to the relevant menus
    if desired.
    The implementation was tested against several minimal
    configs for arm which was created using brute-force.
    There was one regression related to default numbers
    which had their valid range further limited by another symbol.
    config FOO
    	int "foo"
    	default 4
    config BAR
    	int "bar"
    	range 0 FOO
    If FOO is set to 3 then BAR cannot take a value higher than 3.
    But the current implementation will set BAR equal to 4.
    This is seldomly used and the final configuration is OK,
    and the fix was non-trivial.
    So it was documented in the code and left as is.
